openjpeg/src/lib/openjp2/tcd.c, branch v2.3.1 Fork of openjpeg library for JPEG2000 encoding and decoding https://git.carlh.net/cgit/openjpeg/atom?h=v2.3.1 2018-02-11T12:31:04Z Avoid out-of-bounds write overflow due to uint32 overflow computation on images with huge dimensions.

When specified, neither the MCT transform nor JP2 channel transformations will be applied. Tests added for various combinations of whole image vs tiled-based decoding, full or reduced resolution, use of decode area or not.
